• reveals most (and least) economical drivers ahead of National Car Awards
  • All 10 of the least fuel efficient postcodes are in Greater London
  • Orkney and Shetland have most fuel efficient cars

It may have one of the busiest public transport systems in the world, but it seems car fans in England’s capital still choose to keep a little something for the weekend in their garages…

Data released today by Britain’s biggest independent car review site,, shows that when they’re not using tubes, buses or Boris bikes, Londoners love their cars as much as ever - driving some of the least economical and most powerful cars in the country.

The statistics, showing average vehicle MPG figures across the UK from the vehicles included in its database, were revealed ahead of the National Car Awards, due to be announced next month.

With more independent, real-life reviews from car owners than any other site, is a goldmine of car-related data for anyone buying, selling or owning a car, and holds statistics relating to more than 650,000 car owners in the UK.

Using the data, the MPG survey – released today – reveals that all 10 of the least economical postcodes in the UK are inside the notorious M25, with those in Central London scoring an average of just 35.16 mpg against a UK MPG average of 43.28 mpg. Outside of London itself, Kingston upon Thames, Surrey, was the next least economical area – those with a KT postcode averaging 39.30 mpg.

Conversely, Britain’s most economical motorists are in Shetland and Orkney – perhaps because fuel there is frequently the most expensive in Britain and often above £1.50 a litre. Shetlanders averaged 48 mpg, while those in Orkney were marginally behind at 47.16 mpg.

For the British mainland, it seems that the city of Carlisle is the eco-capital – motorists with a CA postcode average 46.88 mpg, while one of the more surprising eco statistics comes in the form of fourth placed Colchester – CO postcode motorists have cars that average 45.98 mpg, or more than 10 mpg better than drivers only a few miles down the M11 in London.

A spokesman for said: “Our survey contains real world statistics submitted by real life car owners, so is a more accurate reflection than any other on Britain’s driving habits. Clearly, Londoners may be very proud of their eco credentials, but I get the impression they’re also quite fond of their luxury or performance cars if the national MPG statistics are anything to go by.”

Further statistics about Britain’s motoring tastes and habits will be announced with the winners of the awards in October. The Awards have the biggest car judging panel in the UK thanks to the input of more than 650,000 independent reviewers. The site is a one-stop resource for car buyers, sellers, owners and enthusiasts, with more real life car data and owner information than any other review site in the UK.

The Awards merit close attention by anyone contemplating buying a car – be it new or second-hand – as well as by everyone in the motor industry.

The spokesman added: “On a uniquely significant scale, this is the voice of the motoring public speaking out about the cars they have bought, and what their experience of them has been.”
